a) 4dm +?dm=1m
70cm+?cm=1m
970mm+?mm=1m

b) 140cm+?cm=20dm
7dm+?cm=1m
60cm+?dm=1m

c)40cm+?mm=1m
6dm+40cm=?dam
8mm+10dm=?mm

Answer 1

4 dm + 6 dm = 1 m
70 cm + 30 cm = 1 m
970 mm + 30 mm = 1 m

140 cm + 60 cm = 200 cm
7 dm + 30 cm = 1 m 
60 cm + 4 dm = 1 m

40 cm + 600 mm = 1 m
6 dm + 40 cm = 1 m = 0.1 dam
8 mm + 10 dm = 8 mm + 100 cm = 8 mm + 1000 mm = 1008 mm
